  1. I think there were two things wrong here: I was not levelling the bed correctly - I was manually moving the z-axis down to the lower limit - which can be slightly different to the printer lowering until the limit switch…

  2. From the linked Configuration.h file the probe X, Y, Z probe offset is set by constant array: So, the sensor is mounted at the right-front (X+, Y- according to the Marlin configuration definition) when facing the…

  3. The problem is that, although you have set the offsets correctly, the boundary limits for the probe to "probe the area" have not been adjusted. It is my belief that this is a flaw in ABL of Marlin 2.0.x.

  4. First, welcome to the 3D Printing Stack Exchange! On bed leveling Bed leveling, or more accurately bed tramming, adjusts the bed so that it is even in relation to the print head.

  5. This is a consequence of enabling Z_SAFE_HOMING : My default Cura start G-code contained this sequence: I changed this to However any oozing will still happen at the center of the build plate, which is a problem.

  6. Eventually it was a mixture of things that sort of solved this. Setting the Z-offset a bit more tight helped some Probing with more gridpoints helped Instead of using glue, I used painterstape.

  7. Finally, after a year I have found a solution! Posting it here in case someone else has the same problem.

  8. Make sure that the bed is level . As the saying goes, a level bed is next to godliness or something like that.

  9. The point of "leveling" (tramming) the bed is to make it: square with the coordinate system of the printer so that it lies in a plane perpendicular to the direction of Z travel, and a known distance from the nozzle tip…

  10. When the printer ignores the scanned topology (grid) of the bed this means that the levelling is not active. G29 activates the M420 to enable the grid. A G28 after scanning the bed will reset this.

  11. The picture is not very clear so this can be related to either: Overextrusion at the bottom layer (slicer setting) or an incorrect bed leveling (bed to nozzle distance too small), or this could be the effect called…

  12. Actual task in your case is to find correct nozzle height for the first layer, so the force for pulling out the paper is not important. It just has to be the same every time you make calibration.

  13. The most likely cause is that your bed just isn't flat. At least as I understand it, delta calibration is not mesh leveling, and is not there to correct for a non-flat bed, just for skew from the bed not being square…

  14. The Prusa printers can do this, based on the maximum and minimum values of X and Y the G-code of the sliced object; M555 will set the bounds of the probing area. However, you need a Prusa printer and use PrusaSlicer.

  15. The bar where the level is attached is the support cross-bar for the X-axis travel. It's important this bar be level, but it's even more important the bar be true to the rest of the machine.

  16. The issue was BLTouch i'm not sure what use is this thing if it cannot compensate for differences in bed or frame. I'm not sure why but the probing seems to be bad.

  17. I have formatted the SD card and installed Octoprint from scratch. That's nasty, because I lost all the models I uploaded. It seems to be a bug in __init__.py of OctoPrint-PrusaMeshMap (archived Github repository).

  19. How much glue do you put on it? I use PVA based spray, barely visible, very evenly spread and no problem whatsoever of sticking paper to the glue layer.

  20. The answer turned out to be that the printer had previously had a different hotend attached, and there was a menu that I'd missed that set the offset for the probe independently from the Z-axis.
